AC Maintenance: Your Questions Answered
AC maintenance questions come up constantly — and they’re usually the same ones. I hear them from homeowners throughout Plymouth and the western Twin Cities suburbs every spring when cooling season gets close and people start wondering whether their system is ready. Here are the honest answers to the ones I get most.
How often should I schedule AC maintenance?
Once a year is the standard recommendation, and spring is the right time — before cooling season starts and while there’s still time to address anything that comes up. A problem caught in May is a quick fix. The same problem in July, when it’s 90 degrees and your system has stopped working, is a whole different situation.
If your system is older or has had recurring issues, a fall check in addition to the spring tune-up isn’t a bad idea. But for most homeowners in good working order, one annual visit covers it.
What’s actually included in a maintenance visit?
A thorough AC tune-up covers the components that affect how well and how safely your system runs — condenser coil cleaning, refrigerant level check, capacitor test, blower motor inspection, thermostat calibration, electrical connections, drain line flush, and filter check. The goal is to confirm everything is functioning correctly and catch anything that needs attention before it becomes a problem.
I cover the full checklist on my AC Tune-Up page if you want the complete breakdown.
What does it cost?
My AC tune-up is $99 — a $120 value. That’s the price for a thorough inspection, not a quick walk-through designed to find reasons to upsell you. If something needs attention during the visit, I’ll tell you what it is, what it will cost to fix, and how urgent it is. You decide how to proceed.
Can I skip it if my system seems fine?
You can — but the things that cause AC failures in the middle of summer often don’t announce themselves in advance. A capacitor that’s weakening, a refrigerant level that’s dropped, a drain line that’s starting to clog — none of these make noise until they become a problem. A tune-up catches them while they’re still minor.
A system that’s been neglected for several years also costs more to run. Dirty coils, restricted airflow, and components working harder than they should all show up in your energy bills over time, even if the system never technically breaks down.
How does maintenance affect how long my system lasts?
A lot, actually. An AC system that’s been properly maintained can last 15 years or more. One that hasn’t tends to wear faster, need more repairs, and fail earlier. The annual tune-up is the single most effective thing you can do to protect that investment.
What should I be doing between visits?
Filter maintenance is the main one. A quality fiberglass filter changed every 30 to 60 days keeps airflow clean and reduces strain on the system. Beyond that, keep the area around your outdoor condenser unit clear of debris and pay attention to anything unusual — smells, sounds, or performance changes worth mentioning when you call.
